About Sara Freder and Pasqualina

Who are Sara Freder and Pasqualina? What are their real identity? What are their actual location/address. Are they scam people? If so, their real motives should be disclosed to all so that none may befall their business of deception and fraudulence. One of my near one has been receiving emails from both Sara Freder and Pasqualina with alluring offers of changing his life with special rituals/talisman for money. I tried to convince him that these people are not honest. But he would not listen. I think there are so many people out there who have been still receiving the same kind of deceiving message from them. This kind of practice should come to an end.
